In this article we will see about ptc creo parametric,\u00a0ptc creo download,\u00a0creo 3.0 download - Student Version.\r\nAbout PTC Creo Parametric :\r\nCreo is a family or suite of design software supporting product design for discrete manufacturers and is developed by PTC. The suite consists of apps, each delivering a distinct set of capabilities for a user role within product development.\r\n\r\nCreo runs on Microsoft Windows and provides apps for 3D CAD parametric feature solid modeling, 3D direct modeling, 2Dorthographic views, Finite Element Analysis and simulation, schematic design, technical illustrations, and viewing and visualization.\r\n\r\nThe software and a primer on using parametric design are available to all students who enroll in the PTC Academic Program.\r\n\r\nRead also:\u00a0Creo vs SolidWorks- Difference Between Creo and Solidworks\r\n\r\nThe PTC University Academic Program is offering free downloads of the PTC Creo Student Edition as well as a free PTC Creo Primer Guide for Students.\r\n\r\nThe primer introduces the modeling, visualization and design tools in PTC Creo Parametric, the company\u2019s flagship 3D CAD software.\r\n\r\ncreo assembly example\r\n\r\nThe primer teaches students how to use PTC Creo Parametric by providing an example of how they might use the software in the real world. Students will be taught how to use PTC Creo Parametric to model two components for a construction kit, a cube and a strut. The guide then explains how to put those two items together to form an assembly and create a photo-realistic rendered image and engineering drawing.\r\n\r\nOther subjects covered in the 101-page PTC Creo Primer Guide for Students include the PTC Creo Parametric interface; Working directories and saving work; Working Directly Theory; opening files; saving files; starting and extrude; creating a sketch; and much more.\r\n\r\nPTC offers a free seat of PTC Creo Student Edition to any student that is part of the PTC Academic Program. The intent of this license is to expand PTC\u2019s opportunity to provide PTC Creo to all students. Included is a one year timed license of PTC Creo Student Edition. Students can use this free software to prepare for class, complete homework assignments, and to become familiar with a product that over 27,000 companies use.\r\n\r\nPTC University Academic Program is giving students and educators all PTC software free of cost with a limited period license. All you need to do is register yourself as student or educator and you are ready to download.\r\n\r\nGo to this link and generate ptc licence:\u00a0https:\/\/www.ptc.com\/en\/academic-program\/products\/free-software","headline":"PTC Creo Parametric Free Download and activate Student licence","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2018-01-18","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2018\/01\/creo-ptc-example-min-300x166.jpg","height":166,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/thermal-expansion-definition-example-types-thermal-expansion/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2018/01/Types-Thermal-Expansion-300x167.jpg')"></div><span class="sr-only">link to Thermal Expansion &#8211; Definition , Example , Types of Thermal Expansion</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/thermal-expansion-definition-example-types-thermal-expansion/">Thermal Expansion &#8211; Definition , Example , Types of Thermal Expansion</a></p></header><div class="excerpt"><p>Thermal Expansion - Definition , Example , Types of Thermal Expansion

This would allow the metallic cover to expand, thereby loosening it to unscrew easily. In case of liquids, you may have observed that mercury in a thermometer rises, when the thermometer is put in a slightly warm water. If we take out the thermometer from the\u00a0warm water the level of mercury falls again.\r\n\r\nSimilarly, in the case of gases, a balloon partially inflated in a cool room may expand to full size when placed in warm water. On the other hand, a fully inflated balloon when immersed in cold water would start shrinking due to contraction of the air inside.\r\nIt is our common experience that most substances expand on heating and contract on cooling. A change in the temperature of a body causes change in its dimensions.\r\n\r\nDefinition Of Thermal Expansion:\r\n\r\n \tThe increase in the dimensions of a body due to the increase in its temperature is called thermal expansion.\r\n \tWhen a material is heated or cooled, it changes its dimensions. Generally, it expands when heated and contracts when cooled although there can be exceptions to this rule.\r\n\r\nTypes Of Thermal Expansion\r\n\r\n \tThe increase in the dimensions of a body due to the increase in its temperature is called thermal expansion.\r\n \tThe expansion in length is called linear expansion.\r\n \tThe expansion in area is called area expansion.\r\n \tThe expansion in volume is called volume expansion\r\n\r\nTypes of Thermal Expansion\r\n\r\nIf the substance is in the form of a long rod, then for small change in temperature, \u0394T, the fractional change in length, \u0394l\/l, is directly\u00a0proportional to \u0394T.\r\n\r\n\u00a0\u0394 l\/l = \u03b1 T 1\r\n\r\nwhere \u03b11 is known as the coefficient of linear expansion and is characteristic of the material of the rod.\r\n\r\nValues of coefficient of linear expansion for some materials\r\n\r\nMaterials\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u03b1l (10\u20135 K\u20131)\r\nAluminium\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a02.5\r\nBrass\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a01.8\r\nIron\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a01.2\r\nCopper\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 1.7\r\nSilver\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 1.9\r\nGold\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 1.4\r\nGlass (pyrex)\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 0.32\r\nLead\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a00.29\r\n\r\nThermal Expansion of water :\r\n\r\nWater exhibits an anomalous behavour; it contracts on heating between 0 \u00b0C and 4 \u00b0C. The volume of a given amount of water decreases as it is cooled from room temperature, until its temperature reaches 4 \u00b0C, [Fig. ]. Below 4 \u00b0C, the volume increases, and therefore the density decreases [Fig. ].\r\n\r\nThermal Expansion of water\r\n\r\nThis means that water has a maximum density at 4 \u00b0C. This property has an important environmental effect: Bodies of water, such as\u00a0lakes and ponds, freeze at the top first. As a lake cools toward 4 \u00b0C, water near the surface loses energy to the atmosphere, becomes denser,\r\nand sinks; the warmer, less dense water near the bottom rises. However, once the colder water on top reaches temperature below 4 \u00b0C, it becomes less dense and remains at the surface, where it freezes. If water did not have this property, lakes and ponds would freeze from the\r\nbottom up, which would destroy much of their animal and plant life.\r\n\r\nPractical Applications of Expansion\r\n\r\n \tWhen rails are laid down on the ground, space is left between the end of two rails.\r\n \tThe transmission cables are not tightly fixed to the poles.\r\n \tThe iron rim to be put on a cart wheel is always of slightly smaller diameter than that of wheel.\r\n \tA glass stopper jammed in the neck of a glass bottle can be taken out by warming the neck of the bottles.\r\n \tThe Eiffel Tower can extend by as much as 12 centimetres if the temperature increases by 40 \u00baC. So if you go to Paris in the summer and stand on top of the Eiffel Tower, you will get a little more height for your money than if you had gone in winter.\r\n \tWhen you first turn on a hot water tap, the water rushes out but is still cold. When it starts to become hot, the flow of water starts to become less and in some cases it stops. This can be explained as follows: the hot water heats the metal valve inside the tap which expands to block off any more flow of water.\r\n \tIf water is gradually cooled, it shrinks in size as expected. But at 3.98 \u00baC it begins to expand again until it turns to ice at 0 \u00baC. This expansion is peculiar to water and is associated with the unusual shape of the water molecule. This behaviour explains why lakes freeze from the top downwards in winter. The colder water is at the top of the lake because it expands and becomes less dense. So when this water freezes it insulates the water below it from the outside cold air like a blanket. It is because of this property many fish can survive the winter rather than becoming part of a giant Popsicle.","headline":"Thermal Expansion &#8211; Definition , Example , Types of Thermal Expansion","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2018-01-17","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2018\/01\/Types-Thermal-Expansion-300x167.jpg","height":167,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/check-valve-diagram-symbol-types-check-valve/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2018/01/ball-type-check-valve-types-of-check-valave-300x118.jpg')"></div><span class="sr-only">link to Check Valve- diagram ,Symbol, Types Of Check valve</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/check-valve-diagram-symbol-types-check-valve/">Check Valve- diagram ,Symbol, Types Of Check valve</a></p></header><div class="excerpt"><p>Check Valve - diagram ,Symbol, Types Of Check valve

Briefly information is given about check valve types, check valve diagram ,symbol used for check valve\u00a0 .\r\nCheck Valve\r\nThe simplest DCV (Direction Control Valve ) is a check valve. A check valve allows flow in one direction, but blocks the flow in the opposite direction. It is a two-way valve because it contains two ports. Figure\u00a0 shows the graphical symbol of a check valve along with its no-flow and free-flow directions.\r\n\r\nSymbol Of Check Valve:\u00a0\r\n\r\nsymbol of check valve\r\nTypes Of Check Valves:\r\nThe various types of check valves are available for a range of applications. These valves are generally small sized, simple in construction and inexpensive. Generally, the check valves are automatically operated. Human intervention or any external control system is not required. These valves can wear out or can generate the cracks after prolonged usage and therefore they are mostly made of plastics for easy repair and replacements.\r\n\r\nClassification of check valves used in hydraulics and pneumatic are as follows :\r\n\r\n \tBall type Check valve\r\n \tPoppet check valve\r\n \tpilot operated check valve\r\n \tshuttle valve\r\n\r\nBall type Check valve\r\n\r\nIn Fig., a light spring holds the ball against the valve seat. Flow coming into the inlet pushes the ball off the seat against the light force of the spring and continues to the outlet. A very low pressure is required to hold the valve open in this direction. If the flow tries to enter from the opposite direction, the pressure pushes the ball against the seat and the flow cannot pass through.\r\n\r\nball type check valve -types of check valve\r\nPoppet check valve\r\nFigure provides two schematic drawings showing the operation of a poppet check valve. A poppet is a specially shaped plug element held on a valve seat by a light spring. Fluid flows through the valve in the space between the seat and poppet. In the free flow direction, the fluid pressure overcomes the spring force. If the flow is attempted in the opposite direction, the fluid pressure pushes the poppet in the closed position. Therefore, no flow is permitted\r\n\r\npoppet check valve -types of check valve\r\n\r\nAdvantages of a poppet valve\r\n\r\n \tVirtually zero leakage in closed position.\r\n \tPoppet elements do not stick even when left under pressure for long periods.\r\n \tFast, consistent response time: typically 15 ms.\r\n\r\nDisadvantages of a Poppet Valve\r\n\r\n \tAxial pressure balance is impossible and considerable force may be needed to open the poppet against the flow at a high pressure. This limits valves that have direct mechanical actuation to low flow duties.\r\n \tGenerally individual poppets are required for each flow path that significantly increases the complexity of multi-port valves.\r\n \tLapping and super finishing of valves add cost.\r\n\r\nPilot-Operated check Valve\r\nA pilot-operated valve along with its symbol is shown in Fig.. This type of check valve always permits free flow in one direction but permits flow in the normally blocked opposite direction only if the pilot pressure is applied at the pilot pressure point of the valve. The check valve poppet has the pilot piston attached to the threaded poppet stem by a nut.\r\nThe light spring holds the poppet seated in a no-flow condition by pushing against the pilot piston. The purpose of the separate drain port is to prevent oil from creating a pressure build-up at the bottom of the piston. The dashed line in the graphical symbol represents the pilot pressure line connected to the pilot pressure port of the valve. Pilot check valves are used for locking hydraulic cylinders in position.\r\n\r\npilot operated check valve\r\n\r\nShuttle Valve\r\nA shuttle valve allows two alternate flow sources to be connected in a one-branch circuit. The valve has two inlets P1 and P2 and one outlet A. Outlet A receives flow from an inlet that is at a higher pressure. Figure 1.5 shows the operation of a shuttle valve. If the pressure at P1 is greater than that at P2, the ball slides to the right and allows P1 to send flow to outlet A. If the pressure at P2 is greater than that at P1, the ball slides to the left and P2 supplies flow to outlet A\r\n\r\ntypes of check valve -shuttle valve , symbol of shuttle valve\r\n\r\nOne application for a shuttle valve is to have a primary pump inlet P1 and a secondary pump inlet P2 connected to the system outlet A The secondary pump acts as a backup, supplying flow to the system if the primary pump loses pressure. A shuttle valve is called an \u201cOR\u201d valve because receiving a pressure input signal from either P1 or P2 causes a pressure output signal to be sent to A.

This machine is needed to wind coils of copper wires up to 18 Gauge. Currently, this process is done manually which is being automated. Automatic plants can work continuously and decreases the gap between the demand and supply. For such a machine there is no need of labour so there is no human error. Without human error, the quality of product is better and cost of production would definitely decreases. Today\u2019s fast growing industries requires an automated machine instead of manually operated machine.\r\n\r\nKeywords\u2014Aluminium former, Ball screw rod, PLC, Proximity Sensors, Servomotor.\r\n\r\nIntroduction to Coil Winding Machine :\r\nThe entire world is rapidly switching to advanced technology like Automation. It is a process in which all the process is done by using different instruments i.e. less man power is involved. So human errors are reduced in this process and hence the system gains high accuracy. All the lengthy processes included in the conventional processes are eliminated in automation process. So time required for getting result is decreased in automation process. Automation gives effective work with less time &amp; less manpower.\r\nNow a day, automation rapidly spreads all over sector for e.g. Agricultural, Industrial, Educational and Robotics etc. Design of Automatic coil Winding Machine is one of the easiest ways to manufacture coil winding for all type of motors and pumps. It is an upgrade version of existing manual coil winding machine. The issues in present version of coil winding machine such as excessive tension in coil while winding, wastage of insulation material in existing controlling mechanism has been overcome in this proposed design of coil winding machine. That is achieved by the use of modern electronic circuits with monitoring devices.\r\n\r\nblock diagram of coil winding machine\r\n\r\n&nbsp;\r\n\r\nIn this project \u201cAUTOMATIC COIL WINDING MACHINE\u201d main objective is to bring out a machine which can implement the idea of automation in Transformer winding or any type of coil windings .Here in real time application let us consider Transformer Manufacturer were the winding is important criterion.\r\nA transformer changes (transforms) an alternating voltage from one value to another. It consists of two coils, called the primary and secondary winding, which are not connected electrically. The windings are either one on top of the other or are side by side on an iron, iron-dust or air core.\r\n\r\nA transformer works by electromagnetic induction: a.c. is supplied to the primary and produces a changing (alternating) voltage in the secondary. It is important that as much as possible of the magnetic field produced by the primary passes through the secondary. A practical arrangement designed to achieve this in an iron-cored transformer. In which the secondary is wound on top of the primary. You should also notice that the induced voltage in the secondary is always of opposite polarity to the primary voltage.\r\nToo large a current in a transformer causes magnetic saturation of the core i.e. the magnetization of the core is a maximum and it is no longer able to follow changes of magnetizing current. Particular care is required when there is a d.c. component.\r\nIn block consists of keypad, Microcontroller, display, Stepper motor, Stepper driver circuit, coil winding machine. This demo works on the basis that the keypad provided is for entering the set values that is the number of windings can be given In case of transformer the primary winding &amp; secondary winding can be entered .All the interfacing with Microcontroller is done through its I\/O lines The Microcontroller used here is 89C51.\r\n\r\nThe Values entered can be monitored in the Display with the display driver circuit which is connected to the Microcontroller the Stepper Motor Is for driving the Winding Machine .The stepper motor is put up by its Driver circuit.","headline":"Design of Automated Coil Winding Machine","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2018-01-16","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2018\/01\/block-diagram-of-coil-winding-machine-300x287.jpg","height":287,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/advantages-disadvantages-wind-enegry-pros-cons-wind-energy/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2018/01/wind-mill-advantages-and-disadvantages-300x188.jpg')"></div><span class="sr-only">link to Advantages and Disadvantages of Wind Enegry-pros and cons of wind energy</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/advantages-disadvantages-wind-enegry-pros-cons-wind-energy/">Advantages and Disadvantages of Wind Enegry-pros and cons of wind energy</a></p></header><div class="excerpt"><p>Advantages and Disadvantages of Wind Energy - pros and cons of wind energy

This section takes a look at the many different advantages of wind energy.\r\n\r\n1.\u00a0 Safe and clean source of energy. - \r\n\r\nThe biggest benefit of wind energy is that it generates electricity while not releasing any harmful pollutants or greenhouse gases as byproducts. This makes it a safe and clean source of energy.\r\n\r\n2. Wind energy is cost competitive with other fuel sources.\r\nThe average levelized price of wind power purchase agreements signed in 2013 was approximately 2.5 cents per kilowatt-hour, a price that is not only cost competitive with new gas-fired power plants but also compares favorably to a range of fuel cost projections of gas-fired generation extending out through 2040.1 Public and private research and development (R&amp;D) can provide continued technological advancements and further reduce wind energy costs\r\n\r\n3. Environmentally Friendly\r\nWind energy is one of the most environmentally friendly energy sources available today. After the manufacture and installation of wind turbines, there will be little to no pollution generated as a result of the wind turbines themselves.\r\n\r\nWind turbines produce no greenhouse gases such as carbon dioxide (CO2) or methane (CH4) which are both known to contribute towards global warming.\r\n\r\nIt should be noted that noise and visual pollution are both environmental factors, but they don\u2019t have a negative effect on the earth, water table or the quality of the air we breathe.\r\n\r\n4.Wind energy can provide income for farmers and ranchers, as well as economic benefits to communities.\r\nWind projects provide revenue to the communities in which they are located via lease payments to landowners, state and local tax revenues, and employment. Even a utility-scale wind turbine has a small footprint, enabling farmers and ranchers who lease their land to developers to continue growing crops and grazing livestock. As wind energy systems continue to expand, they provide significant economic benefits. A recent study found that, on average, wind power installations within the study area and occurring between 2000 and 2008 resulted in an increase in total county-level personal income of approximately $11,000 per megawatt\r\n\r\n5.Wind Energy is Free\r\nUnlike some other energy sources, wind energy is completely free. There\u2019s no market for the supply and demand of wind energy, it\u2019s there to be used by anyone and will never run out. This makes wind energy a viable option for generating cheap electricity.\r\n\r\n6.Wind energy is an inexhaustible renewable energy source.\r\nWind energy is plentiful and readily available, and capturing its power does not deplete our natural resources. Improved technologies and taller turbines allow wind deployment in areas with lower wind speeds, such as in the southeastern United States. In addition, offshore wind has tremendous energy potential.\r\n\r\n7.\u00a0Wind turbines do not consume water.\r\nMost electric power plants require water to operate, but producing electricity from the wind does not require water. Researchers estimate that wind power generation in 2013 reduced powersector water consumption by 36.5 billion gallons.\r\n\r\n8.\u00a0Wind energy systems have low operating costs.\r\nWind energy systems have low operating expenses because there are no associated fuel costs. When large amounts of wind energy are added to the grid, additional generation may be required to accommodate wind energy\u2019s variability, but leading experts in the field concluded that system operating cost increases from wind variability and uncertainty amounted to only about 10% or less of the wholesale value of the wind energy and that there are ways to reduce these costs.The absence of fuel cost also protects consumers from fluctuating coal and natural gas costs.\r\n\r\n9.\u00a0Wind energy creates jobs.\r\nWind energy development creates thousands of long-term, high-paying jobs in fields such as wind turbine component manufacturing, construction and installation, maintenance and operations, legal and marketing services, transportation and logistical services, and more.\r\n\r\n10. Huge Potential\r\nWind energy has huge potential. It\u2019s both renewable and sustainable and is present in a wide variety of places. Although a significant level of wind energy is required to make a wind turbine installation cost effective, the technology isn\u2019t limited to just a handful of locations such as is the case for geothermal power stations.\r\n\r\n11.\u00a0Wind energy can be used in a variety of applications.\r\nWind turbines can be used in a variety of applications. Utility scale wind farms can provide electricity to an entire community while smaller turbines, often described as being used in \u201cdistributed applications,\u201d can be installed at or near a site where the electricity will be used. Community wind projects include turbines for schools, tribes, municipal utilities, and rural electric cooperatives. Small wind turbines, alone or as part of a hybrid system, can power homes, businesses, farms, ranches, and schools. Wind energy can be perfect for remote applications such as water pumping, ice making, and telecommunications sites, and can displace diesel fuel in remote communities.\r\nDisadvantages of Wind Energy- Cons of Wind Energy:\r\nSo, we\u2019ve seen the advantages, now it\u2019s time to take a look at the main disadvantages of wind energy.\r\n\r\n1. Unpredictable-Wind does not always remain consistent.\u00a0\r\nWind is unpredictable and the availability of wind energy is not constant. Wind energy is therefore not well suited as a base load energy source. If we had cost-effective ways of storing wind energy the situation would be different.\r\n\r\nWe can hope for breakthroughs in energy storage technologies in the future, but right now, wind turbines have to be used in tandem with other energy sources to meet our energy demand with consistency.\r\n\r\n2. Wildlife: \r\n\r\nWind turbines may be dangerous to flying animals. Many birds and bats have been killed by flying into the rotors. Experts are now conducting research to learn more about the effects that wind turbines have on marine habitats.\r\n\r\n3. Noise Pollution\u00a0\r\nNoise is a problem for some people that live in the proximity of wind turbines. Building wind turbines in urban environments should be avoided. Noise is not a problem with offshore wind turbines at all. New designs show significant improvements compared to older models and generate less noise.\r\n\r\n4. Suitable to Certain Locations\r\nWind energy can only be harnessed at certain locations where speed of wind is high. Since they are mostly setup in remote areas, transmission lines have to be built to bring the power to the residential homes in the city which requires extra investment to set up the infrastructure.\r\n\r\n5.Storage Issues: \r\n\r\nGoing along with the point of turbines being inefficient, they are unable to store converted energy in large amounts. Being that wind only comes in fits and starts, in order to be efficient, the turbines would need to store up these bursts of wind energy to be truly effective, but because they can\u2019t, they are not as efficient as they may seem to be.\r\n\r\n6.\u00a0Installation Costs: \r\n\r\nAs you can imagine, installing a group of these huge turbines can cost a lot of money. Installing just one of them can be as pricey as $2 million or more, with more costs coming for maintenance. Another cost in installing a turbine is less a monetary issue as it is an environmental one. The production, transport, and installation of one these turbines has a sizable \u201ccarbon footprint\u201d, which is important to know, especially considering that the whole idea behind its construction is for clean power.","headline":"Advantages and Disadvantages of Wind Enegry-pros and cons of wind energy","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2018-01-15","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2018\/01\/wind-mill-advantages-and-disadvantages-300x188.jpg","height":188,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/mechanical-energy-definition-mechanical-energy-examples/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2018/01/Mechanical-Energy-Examples-steam-turbine-300x150.jpg')"></div><span class="sr-only">link to Mechanical Energy Definition- Mechanical Energy Examples</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/mechanical-energy-definition-mechanical-energy-examples/">Mechanical Energy Definition- Mechanical Energy Examples</a></p></header><div class="excerpt"><p>Mechanical Energy Definition- Mechanical Energy Examples

It is the energy associated with the motion and position of an object. The principle of conservation of mechanical energy states that in an isolated system that is only subject to conservative forces, the mechanical energy is constant. If an object is moved in the opposite direction of a conservative net force, the potential energy will increase and if the speed (not the velocity) of the object is changed, the kinetic energy of the object is changed as well. In all real systems, however, nonconservative forces, like frictional forces, will be present, but often they are of negligible values and the mechanical energy's being constant can therefore be a useful approximation. In elastic collisions, the mechanical energy is conserved but in inelastic collisions, some mechanical energy is converted into heat.\r\n\r\nMechanical energy can be classified as potential energy or kinetic energy.\r\nPotential energy is energy that is stored in an object. The different types of mechanical potential energy are related to the position of the object.\r\nGravitational potential energy is related to the object's height above the ground. The higher an object is above the ground, the higher the potential energy of the object.\r\nElastic potential energy is related to how far an object is stretched. For example, rubber bands have elastic potential energy.\r\nKinetic energy is energy of motion. The amount of kinetic energy that an object has depends on the mass and velocity (or speed) of the object. For example, a car moving at 60 miles per hour has more kinetic energy than the same car moving at 30 miles per hour.\r\nThe Total Mechanical Energy\r\n\r\nMechanical energy of an object can be the result of its motion (i.e., kinetic energy) and\/or the result of its stored energy of position (i.e., potential energy). The total amount of mechanical energy is merely the sum of the potential energy and the kinetic energy. This sum is simply referred to as the total mechanical energy (abbreviated TME).\r\n\r\nTME= PE+ KE\r\nMechanical Energy Examples\u00a0 :\r\nToday, many technological devices convert mechanical energy into other forms of energy or vice versa. These devices can be placed in these categories:\r\n\r\n \tAn electric motor converts electrical energy into mechanical energy.\r\n \tA generator converts mechanical energy into electrical energy.\r\n \tA hydroelectric powerplant converts the mechanical energy of water in a storage dam into electrical energy.\r\n \tAn internal combustion engine is a heat engine that obtains mechanical energy from chemical energy by burning fuel. From this mechanical energy, the internal combustion engine often generates electricity.\r\n \tA steam engine converts the heat energy of steam into mechanical energy.\r\n \tA turbine converts the kinetic energy of a stream of gas or liquid into mechanical energy.\r\n\r\nMechanical Energy Examples\u00a0-steam turbine\r\n\r\nMechanical Energy Example :\u00a0\r\nLet\u2019s work through an example of calculating mechanical energy using a pendulum.\r\nThe formula to calculate the potential energy is:\r\nPE = mgh\r\n\r\nSubstitute the values into the formula and you get:\r\nPE = 10 kg x 0.2 m x 9.8 m\/s2 = 19.6 J\r\n\r\nWhenever the ball is at the ends, the Potential Energy (PE) = 19.6 J. Since the speed is 0 at the end (remember the ball stops at each end), the Kinetic Energy (KE) = 0 J.\r\n\r\nThe total mechanical energy, ME, of the pendulum at either end would be:\r\n\r\nME = KE + PE = 0 J + 19.6 J = 19.6 J\r\n\r\nmechanical energy example -pendulum\r\n\r\nAs the ball approaches the middle position, the PE is decreasing while the KE is increasing. At exactly halfway, the height of the ball will drop to zero. This would mean that PE would also equal zero. At this point, theoretically, all PE has transformed (turned) into KE. This would make the KE = 19.6 J while the PE = 0 J. The mechanical energy would be similar to the ends equaling 19.6 J:\r\n\r\nME = KE + PE = 19.6 J + 0 J = 19.6 J\r\n\r\nThe key word in the last paragraph was \u201ctheoretically.\u201d In a perfect closed system, as the PE decreases, it all turns into KE. As KE decreases, it all turns back into PE. A closed system is very similar to the closed system we discussed in chemical and physical changes. In this case, a closed system refers to a group of objects that transfer energy only to each other.","headline":"Mechanical Energy Definition- Mechanical Energy Examples","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2018-01-13","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2018\/01\/Mechanical-Energy-Examples-steam-turbine-300x150.jpg","height":150,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <nav class="pagination-wrapper" aria-label="article pagination"> <a class="prev page-numbers" href="?page_num=209">&laquo; PREV</a> <a class="page-numbers" href="?page_num=1"><span class="screen-reader-text">Page </span>1</a> <span class="page-numbers dots">&hellip;</span> <a class="page-numbers" href="?page_num=208"><span class="screen-reader-text">Page </span>208</a> <a class="page-numbers" href="?page_num=209"><span class="screen-reader-text">Page </span>209</a> <span aria-current="page" class="page-numbers current"><span class="screen-reader-text">Page </span>210</span> <a class="page-numbers" href="?page_num=211"><span class="screen-reader-text">Page </span>211</a> <a class="page-numbers" href="?page_num=212"><span class="screen-reader-text">Page </span>212</a> <span class="page-numbers dots">&hellip;</span> <a class="page-numbers" href="?page_num=338"><span class="screen-reader-text">Page </span>338</a> <a class="next page-numbers" href="?page_num=211">NEXT &raquo;</a></nav></section></main><aside id="secondary" class="widget-area"><div class="about-wrapper"><h2 class="widget-title" style="background: #d693c6; color: #ff392e">About Us</h2><div class="about-image" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2020/03/Sachin-Thorat-300x300-min.png')"></div><p class="about-copy">LearnMech.Com is a Mechanical Project-oriented platform run by Sachin Thorat who is a B-Tech Graduate in Mechanical Engineering.
